I have the lovely misfortune of working at Walmart and I just found this out yesterday. They've decided to be a bit nazi like in their sales of the 360. First off if you're in line and you go to the bathroom, or leave it for any other reason you lose your place in line. Second you can't have anyone hold your place in line. Today the district manager is calling our store manager and everyother store manager in the district and will most likely be dumping off more rules.
I remember things being alot more civil at Walmart when the first XBox came out. Of course Walmart has gone from being pricks to outright jerkoffs these past few years. I remember the first XBox launch because I was working that night and I called dad from work an asked him to come down an sit in line and pick me up one. Everyone that came in time got a number and that was that, no fighting, no you're screwed if you get up to go to the bathroom.
Somehow I just see fights breaking out at Walmart because of this kinda stuff.
